We recently stayed at Flow Villa and it could not have been more perfect for our group. We traveled to Nosara with friends, there were 7 of us all together, three couples plus one additional friend.
We were all very comfortable in this house. There are four identical bedrooms, two upstairs and two down. Each has their own bedroom. Honestly, the accommodations were just perfect.
The bedrooms are all comfortable, they all have their own bathroom, and they are airconditioned as well.
The kitchen, living room, patio, and pool make for great communal hangout spots and Flow is right in the heart of Nosara. It was easy for us to walk anywhere and this allowed for an easy transition between group activities, couple activities, and even solo adventures.
The internet was not working during our stay (it was repaired on the last day), but we were okay with that and actually made for a more relaxing trip.
There were some ants in the house but honestly, listen, you're in the jungle. This has been true everywhere I've stayed in Nosara.
Beyond that, you absolutely must have Graciela come and make dinner for you and your group if you stay here. Her food is incredible, and it's also a great value. We honestly would have had her cater two dinners had we known it was going to be so good. I am saying this having tried most of the upscale restaurants in Nosara and I was a professional chef for 15 years. You won't regret it. At the very least, order her ceviche and guacamole.
The house is safe, modern, and truly has all that you'd need.
Highly recommended.
